G'Day Tony

Many thanks for the input.  I had never heard of openvpn and having 
googled a little on the topic, this seems to be a pretty sound option 
although, setting openvpn up seems somewhat daunting for someone with my 
fairly low level of understanding of the finer points of moving data 
around networks.  Never the less, I have found a couple of "How Tos" on 
this topic and I will give this a go over the next few days and see if I 
can make it work.

Just an update for all on my original post,  I decided to have a go at 
setting up tunneled SSH from Wagga to my desktop as a way to learn the 
processes involved and as of a couple of evenings ago, my Wagga based 
family were able to logon to my desktop and copy a file.  This for me is 
a milestone!

Thanks again to all for the input.  Back now to the keyboard.......now 
wheres my specs........
